BLOCKING TENDENCY IS MOST COMMONLY OBSERVED IN PRODUCTION OF THIN LDPE. LLDPE FILMS AT HIGHER PROCESSING TEMPERATURES AND DUE TO HIGH WINDING TENSIONS BLOCKING TENDENCY INCREASES WITH CORONA TREATMENT OF THESE FILMS.

ADDITION OF ANTIOXIDANT MASTERBATCH IN VIRGIN MATERIAL INCREASES THE OXIDATION INDUCTION TIME (OIT) VALUE WHICH IS INDICATION OF TIME TAKEN FOR PLASTICS TO START DEGRADATION. DURING REPROCESSING OF PLASTICS ADDITION OF ANTIOXIDANT M/B HELPS IN RETAINING THE MECHANICAL PROPERTIES OF THE END APPLICATION WHICH WOULD OTHERWISE DETERIORATE.

THIS CONTAINS A SPECIAL COMBINATION OF FILLERS TO INCREASE STIFFNESS TO EXTRUDED/MOULDED PRODUCTS. THIS MASTER BATCH IS PARTICULARLY USEFUL FOR BOX STRAPPINGS. WHERE BESIDES INCREASING THE STIFFNESS IT ALSO IMPROVES THE EMBOSSING AND IMPARTS ANTI-SPLITING PROPERTIES. IT CAN ALSO BE USED IN INJECTION MOULDING TO INCREASE SOME STIFFNESS AND WEIGHT.
